Se denomina “energías renovables” a aquellas fuentes energéticas basadas en la utilización del sol, el viento, el agua o la biomasa vegetal o animal -entre otras-. Se caracterizan por no utilizar combustibles fósiles –como sucede con las energías convencionales-, sino recursos capaces de renovarse ilimitadamente.

Explanation:
Add radio labeled actin sub units to a mixture of actin filaments in which conditions are favorable for polymerization. This would enable you to identify the plus end of actin filaments. 
Actin filaments are linear polymer of globular actin sub units Actin filaments have polarity. This means that the two ends can be identified due to structural differences.
